We truly wish we could add items to your order after it's been placed, but our current system is designed to ensure your order is processed quickly and accurately. This, unfortunately, means we can't make changes or additions once it's been finalised.
We apologise for any inconvenience this may cause and recommend taking a moment before checkout to ensure everything is in your shopping cart. It's a little step that can save needing to place a separate order and incurring an additional shipping cost.
